Kelly,

You really love this stuff!

Last year, or was it the year before, I used some of Arlon's ("liscensed from Rogers") CLTE
with better than fair results from Multek and Praegetzer. You know the stuff has a Dk of 2.8
and is composed of a ceramic slurry (chunky peanut butter) impregnated into a glass support
fabric (106 style). It's not too different than the Rogers formulation (probably the same now
that Rogers has its own treaters?) but is supported.

The two suppliers mentioned made my 8 layer MLB work well at some fairly high frequencies.
Another supplier made MLB's with "mush" throughout. You know it all depends on how well
processes are managed.
